Description

Technical Field

[0001] This utility model relates to the field of shelving, specifically to a reversing track for a three-dimensional warehouse shelving system. Background Technology

[0002] As an important logistics storage device, automated storage and retrieval system (AS / RS) racking, particularly four-way racking, is a type of continuous intelligent storage and retrieval racking that is not divided by aisles.

[0003] On four-way racking systems, palletized goods are transported and stored according to instructions from the control center, resulting in a high degree of intelligent storage. When transporting goods, the four-way carts move along tracks. When the lateral and longitudinal paths intersect, a reversing track is needed to coordinate with the four-way carts to change their direction of travel. Existing reversing tracks, such as... Figure 7 As shown, during reversal, the rollers of the four-way vehicle pass through a 90° track opening. The left and right ends of this track opening belong to different components. Installation errors in these two components can cause slight deviations in the horizontal height between the reversing track and the sub-track. If this deviation is too large, the four-way vehicle will generate significant noise and impact during reversal, which can severely affect the stability of its operation. Therefore, the design of the reversing track affects the stability and operating efficiency of the four-way vehicle during reversal. Utility Model Content

[0004] The purpose of this invention is to provide a reversing track for a three-dimensional warehouse racking system, which makes the reversing span of the four-way vehicle rollers more stable and reduces the impact on the operation of the four-way vehicle.

[0005] To achieve the above objectives, this utility model provides a reversing track for a three-dimensional storage rack. The reversing track includes two main tracks extending in a first direction mounted on a track frame. Two reversing tracks extending in a second direction and fixed to the track frame are disposed between the two main tracks. Supporting rectangular tubes extending in the same direction as the reversing tracks and fixed to the track frame are disposed on the outer side of each main track. A gap is formed between the reversing tracks and the supporting rectangular tubes, passing through the main tracks. The distance of this gap is greater than the width of the main tracks. The upper surface of the supporting rectangular tubes is higher than the upper surface of the main tracks. The outer ends of the supporting rectangular tubes are all connected to corresponding sub-tracks. The upper surfaces of the supporting rectangular tubes, the sub-tracks, and the reversing tracks are flush. The first direction is perpendicular to the second direction.

[0006] Preferably, the track frame includes two first rectangular tubes welded to the reversing track, and two second rectangular tubes fixed to both ends of the two first rectangular tubes.

[0007] Preferably, the lower surface of the second rectangular tube is lower than the lower surface of the first rectangular tube, a first fixing plate is welded to the connection between the lower surface of the second rectangular tube and the first rectangular tube, a second fixing plate is provided between the first fixing plate and the first rectangular tube, the second fixing plate is welded to the lower surface of the first rectangular tube, and the first fixing plate and the second fixing plate are respectively fixed on both sides of the first rectangular tube by a first bolt and a matching first nut.

[0008] Preferably, a third fixing plate is welded to the left and right sides of both ends of the first rectangular tube, and the third fixing plate is fixed to the second rectangular tube by a second bolt and a matching second nut. The second bolt passes through the third fixing plate and the second rectangular tube in sequence.

[0009] Preferably, the sub-track is welded with first corner plates on both sides facing one end of the supporting rectangular tube. The bottom surface of the first corner plate is fixed to the second rectangular tube by a third bolt and a matching third nut. The third bolt is arranged to pass through the bottom surface of the first corner plate and the second rectangular tube in a vertical direction.

[0010] Preferably, the bottom surface of the mother track is supported on the first rectangular tube, and second corner plates are welded to both sides of the connection position between the mother track and the first rectangular tube. The bottom surface of the second corner plate is fixed to the first rectangular tube by a fourth bolt and a matching fourth nut. The fourth bolt is arranged to pass through the bottom surface of the second corner plate and the first rectangular tube in a vertical direction.

[0011] Preferably, the first rectangular tube has triangular plates welded and fixed to the bottom surface of the mother track on both sides. The third triangular plates are fixed to the first rectangular tube by a fifth bolt and a matching fifth nut. The fifth bolts are horizontally inserted through the vertical surfaces of the third triangular plates on both sides and the first rectangular tube.

[0012] Preferably, the main track, the sub-track, and the reversing track are all rectangular steel pipes.

[0013] According to the above technical solution, this utility model provides a reversing track for a three-dimensional storage rack. The reversing track includes two main tracks extending in a first direction mounted on a track frame. Two reversing tracks extending in a second direction and fixed on the track frame are arranged between the two main tracks. Supporting rectangular tubes extending in the same direction as the reversing tracks and fixed on the track frame are arranged on the outer side of the main tracks. A gap is formed between the reversing tracks and the supporting rectangular tubes, which passes through the main tracks. The distance of the gap is greater than the width of the main tracks. The upper surface of the supporting rectangular tubes is higher than the upper surface of the main tracks. The outer ends of the supporting rectangular tubes are all connected to the corresponding sub-tracks. The upper surfaces of the supporting rectangular tubes, the sub-tracks, and the reversing tracks are flush. The first direction is perpendicular to the second direction.

[0014] When the automated storage and retrieval system (AS / RS) racking system operates with four-way trolleys reversing, the rollers on both sides of the trolley initially travel along two main tracks. Upon reaching the reversing point, the rollers on the front and rear sides of the trolley switch onto the reversing track and continue traveling along it. When crossing the gap between the supporting rectangular tube and the main tracks, the support rectangular tube and the reversing track are welded and fixed to the track frame during manufacturing, resulting in flush surfaces and no height difference. This ensures a smoother crossing of the gap and reduces the impact of the reversing point on the trolley. Consequently, this reduces noise during reversal and improves the stability and operational efficiency of the four-way trolley.

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0028] See Figure 1-6 The illustrated reversing track of the automated storage rack includes two main tracks 1 extending in a first direction mounted on a track frame. Two reversing tracks 2 extending in a second direction and fixed to the track frame are arranged between the two main tracks 1. Supporting rectangular tubes 5 extending in the same direction as the reversing tracks 2 and fixed to the track frame are arranged on the outer side of each main track 1. A gap 4 is formed between the reversing tracks 2 and the supporting rectangular tubes 5, passing through the main tracks 1. The distance of the gap 4 is greater than the width of the main tracks 1. The upper surface of the supporting rectangular tubes 5 is higher than the upper surface of the main tracks 1. The outer ends of the supporting rectangular tubes 5 are all connected to corresponding sub-tracks 6. The upper surfaces of the supporting rectangular tubes 5, the sub-tracks 6, and the reversing tracks 2 are flush. The first direction is perpendicular to the second direction.

[0029] Through the implementation of the above technical solution, when the four-way vehicle is reversing, the reversing track of the automated storage and retrieval system first has a set of rollers on the left and right sides of the four-way vehicle traveling on the two parent tracks 1. When it reaches the reversing point, a set of mixed rollers on the front and rear sides of the four-way vehicle is supported on the reversing track 2 and travels on the reversing track 2. When it crosses the interval 4 formed between the support rectangular tube 5 and the parent track 1, since the support rectangular tube 5 and the reversing track 2 are welded and fixed to the track frame during production, their upper surfaces are flush and there is no height difference, making the four-way vehicle more stable when crossing this interval 4, which can reduce the impact on the four-way vehicle at the reversing point. This can reduce the noise of the four-way vehicle during reversing and improve the stability and operating efficiency of the four-way vehicle during reversing.

[0030] In this embodiment, to further provide a track frame, the track frame includes two first rectangular tubes 3 welded to the reversing track 2, and two second rectangular tubes 7 fixed to both ends of the two first rectangular tubes 3. The second rectangular tubes 7 extend along a first direction and are connected and fixed to the rack body. The two ends of the first rectangular tubes 3 are aligned with the outer ends of the supporting rectangular tubes 5, providing support for the supporting rectangular tubes 5 at both ends and for the reversing track 2.

[0031] In this embodiment, to further provide a detachable connection between the first rectangular tube 3 and the second rectangular tube 7, the lower surface of the second rectangular tube 7 is lower than the lower surface of the first rectangular tube 3. A first fixing plate 8 is welded to the connection between the lower surface of the second rectangular tube 7 and the first rectangular tube 3. A second fixing plate 22 is provided between the first fixing plate 8 and the first rectangular tube 3. The second fixing plate 22 is welded to the lower surface of the first rectangular tube 3. The first fixing plate 8 and the second fixing plate 22 are fixed on both sides of the first rectangular tube 3 by a first bolt 9 and a matching first nut 13, respectively.

[0032] In this embodiment, a third fixing plate 23 is welded to the left and right sides of both ends of the first rectangular tube 3. The third fixing plate 23 is fixed to the second rectangular tube 7 by a second bolt 11 and a matching second nut 12. The second bolt 11 passes through the third fixing plate 23 and the second rectangular tube 7 in sequence. With this arrangement, the first rectangular tube 3 and the second rectangular tube 7 are connected vertically and horizontally at each connection position using two first bolts 9 and two second bolts 11, respectively, thereby improving the connection stability.

[0033] In this embodiment, to further provide a connection method between the sub-track 6 and the second rectangular tube 7, the sub-track 6 has first corner plates 15 welded to both sides facing one end of the supporting rectangular tube 5. The bottom surface of the first corner plate 15 is fixed to the second rectangular tube 7 by a third bolt 14 and a matching third nut 10. The third bolt 14 is arranged to pass through the bottom surface of the first corner plate 15 and the second rectangular tube 7 in a vertical direction.

[0034] In this embodiment, the bottom surface of the main track 1 is supported on the first rectangular tube 3. Second corner plates 16 are welded to both sides of the connection point between the main track 1 and the first rectangular tube 3. The bottom surface of the second corner plates 16 is fixed to the first rectangular tube 3 by a fourth bolt 17 and a matching fourth nut 18. The fourth bolt 17 is vertically inserted through the bottom surface of the second corner plate 16 and the first rectangular tube 3. This arrangement allows the main track 1 to be detachably mounted on the first rectangular tube 3. Since the distance of the interval 4 is greater than the width of the main track 1, the distance between the main track 1 and the side of the interval 4 should be set to allow the fourth bolt 17 to be inserted.

[0035] In this embodiment, the first rectangular tube 3 has triangular plates 20 welded and fixed to the bottom surface of the mother track 1 on both sides. The triangular plates 20 are fixed to the first rectangular tube 3 by fifth bolts 19 and matching fifth nuts 21. The fifth bolts 19 are horizontally inserted through the vertical surfaces of the triangular plates 20 on both sides and the first rectangular tube 3. With this arrangement, in conjunction with the second triangular plate 16, the mother track 1 and the first rectangular tube 3 are fixed at the connection position in four directions.

[0036] In this embodiment, to further provide a mother track 1, a sub-track 6, and a reversing track 2, the mother track 1, the sub-track 6, and the reversing track 2 are all rectangular steel pipes.
